Fruta del Norte is a completely concealed and extraordinarily well preserved epithermal gold-silver deposit located in the remote Cordillera del Cóndor mountain ranges of southeastern Ecuador. Currently defined resources in a single, steep, relatively small body, displaying exceptional grade continuity, contain 9.81 million ounces (Moz) of gold and 15.0 Moz of silver, with an indicated resource grade of 9.59 g/t Au and 12.9 g/t Ag. The deposit was discovered in early 2006 during a greenfields program conducted by Aurelian Resources, a Canadian junior explorer. Discovery resulted from systematic drill testing of a conceptual geologic model, which predicted that auriferous veins would be present in andesitic volcanic rocks inferred to underlie a steep silicified rib cutting a fluvial conglomerate sequence.

Geochemistry is the study of the development, and distribution of chemical elements on Earth, which are found in rock-forming minerals and their byproducts, as well as in living beings, water, and the environment. The elemental geochemical variation of sediments is used to recognize the mechanisms controlling the estuarine environment and serves as a baseline for assessing the environmental effect in the future. Geochemistry is a unique field that deals with the study of mineral deposits.

Crystal growth of diamonds at the Earth’s mantle depths of 150–800 km had been accompanied by a fragmentary capturing minerals, melts and volatile compounds (as diamond-hosted inclusions) from the parental melts. This indicates convincingly that diamonds were originated jointly with the phases of primary hermetic inclusions in a common parental medium. This opens up possibilities for evaluating the general chemistry of natural diamond-producing systems from the compositions of significantly different phases associated with diamonds in primary inclusions. Of particular value is that it has been made possible to determine the boundary compositions for the experimental systems which duplicate the natural ones responsible for genesis of diamonds and associated phases. As a consequence, the principal problems of diamond genetic mineralogy may be formulated. It became apparent, that the methodology of physico-chemical experiments is of crucial importance in solution of the genetic problems for diamonds and associated phases. <...>

Economic Geology is an important branch of Geology which deals with different aspects of economic minerals being utilised by mankind to fulfill his various needs. The economic minerals are those which can be extracted profitably. The subject provides detailed knowledge of r'l these minerals, like their origin, process of formation, mutual relations and time sequence, control of localisation, metallogemc epoch and province, and classification, besides their mineralogy, uses, modes of occurrence, geological and geographical distribution, reserves, production and all other related facts. <...>

The Cadia Ridgeway deposit is one of a group of porphyry-style deposits discovered since 1992 by Newcrest geologists at Cadia 20 kms south of Orange in the central tablelands of New South Wales, Australia. The Ridgeway deposit lies 500m below the surface, 3 kms north-west of the Cadia Hill open cut mine, and was discovered in November 1996. It is notably rich in Au with an inferred and indicated resource of 44 Mt at 2.6 g/t Au and 0.82% Cu, and is under development as an underground mining operation. <...>
